After each test, the exhaust gas will spread in the laboratory air, and there will be this exhaust gas smell in the laboratory air.

[0003] At present, the solution to experimental exhaust gas is mainly to conduct the experiment in a fume hood. However, since the gas spreads quickly and widely, there is no way to completely exhaust the exhaust gas. Moreover, the fume hood converts indoor air with outside air, and the exhaust gas is still polluted when discharged to the outside. Therefore, a gasoline oil sample-based simulated test exhaust gas treatment device and method are needed to solve the above problems. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, the exhaust gas generated in the simulation test process of the intake valve sediment of the intake port injection gasoline engine enters the condenser box through the air inlet, and the condensation system composed of the compressor, the radiator, the capillary tube, the drying filter and the condenser box cooperates with each other to liquefy part of the gas in the condenser box into liquid, and the waste liquid converted by the exhaust gas flows into the waste liquid recovery bottle through the waste liquid outflow port for unified recovery, and part of the exhaust gas that is not converted into liquid is separated three times by three oil-water separators, and then filtered twice by two activated carbon filters to obtain fully filtered gas that meets the standards, and then released into the air through the air outlet, so that the treated gas is not easy to pollute the air;
